Great for long walk 👍
These are super comfortable and perfect for long walk. On weekends, I walk to & from work for 13 miles total 🤯 wearing these pairs and never has blisters or joint pain. They are comfortable and have enough cushion for your ankles. I also run on them on trademill and they seem to handle the impact when your foot landed on the running deck. The upper part of the shoe is made of elastic fabric which allows easy stretching and tight fit. Great shoes and would recommend it.

Light weight, comfortable. Runs a touch small
These are great looking, very supportive, and comfortable sneakers. I’d say they run a just a tiny bit small. I’m usually a 10.5-11, and these 11s are in the snug side. Not so tight that they won’t break in, and I’m definitely keeping them. Just saying if you’re between sizes, you might wanna round up a half size.

Great Pair Of Shoes
Not exactly sure who sold this, I suppose I assumed it was from Amazon, but it came in a sealed bag and no box, and that's a first for me from Amazon. It is pretty standard from ebay however...but again, I didn't order them thru anywhere else. Maybe it was in the description and I missed it? I am not particularly upset about it because the price was definitely less than I saw the same pair for (brand new) anywhere else online...so don't let that color your opinion here. They arrived timely, which is always nice. They are comfortable, which I expect from Adidas. In all the years I've purchased shoes from them, only once have I been disappointed in the fit. But that does not count here. I wasn't uber keen on the color, but again, the price made me willing to deal with it because that isn't ultimately the main reason you should buy a pair of shoes. The Ultraboost shoes have an abundance of the foam that Adidas uses to cushion your heels in particular while walking/running and it does a pretty good job. If I had to point to the pair of shoes I own that has the most cushioned experience, I'd say it was the recent pair of OneMix running shoes I got shortly before Christmas. I would've guessed these were just as cushiony, but they aren't. That doesn't mean they aren't good though. They envelop your feet and fit well - although I should point out if you have wide feet, you're going to want to hold off until you can get a pair that isn't as narrow as these. I have fairly narrow feet and they are a very close fit for me. I am really warming up to shoes that do not come with a traditional tongue. It took me a bit to get used to the design but honestly, they don't feel any different in my opinion. They are comfortable (at least the ones are that I own) and I will definitely be buying more in the future. In short, great shoes and great fit, but keep in mind if you have a wide foot before buying and good luck!

Should you buy these?
I skeptically bought these shoes thinking they might be potential fakes, to my surprise they are either 100 percent authentic or amazingly recreated pairs . I checked for any glue marks, the knitting, and branding on my all white pairs and everything is in line with Authentic ultraboost21’s. My experience with these so far (about 1-2 weeks in): The first wear they might feel a little tight around the toes compared to older models, but it quickly goes away by the second wear. Quality and comfort is what to be expected for any ultraboost, amazing. I use these shoes for workouts, everyday wear around campus, and running and they always meet expectations. Aside from that the styling is amazing and very versatile with what ever you wear. Over all I am an ultraboost lover, and being able to get them at this price is amazing. Hopefully this was able to help anyone make a decision on purchasing. 100 percent recommend buying these shoes, if you’re thinking about it just pull the trigger you won’t be disappointed!

Comfy shoe that is wider than Nike
I wear this shoe for light running 2-3 miles at a time, working out, and just wearing around casually. I purchased these as I was at a total loss on dealing with a Neuroma in between my 3rd and 4th toe. I picked these up as Nike, Under Armor was a tighter fitting shoe and caused me alot of pain. These work great and I love the balance of the cushion and the stiffness not being a total flex shoe. This shoe just made me a Adidas fan again and I will pretty much always stay away from Nikes now due to the narrow fit.

Overall a good product
Nice looking shoe, high quiality materials, boost and more boost, very comfortable shoes. There are other products on the market that are a lot lighter than this one so if you are looking this for performance I advise to choose a different one, since they are heavier, otherwise they will perform excellent for other kind of activities or casual wear. They also feel a little rigid(firm) on the cushion compared to previous ultra boost versions, still very cloudy and confortable to carry on. Finally the aesthetics are great so I totally recommend the product for casual wear.

I've bought Ultraboost sneakers for years and years. However, for 21, Adidas decided to seam in the toe box, whereas the older models had flexible primeknit mesh or whatever they called it. It's too tight and digging into my big toe, and will not break in. Completely unwearable.

These are great shoes for running, jogging, and walking. I used an older version for several years. I needed to replace them and I purchased a couple of other shoes, but none came even closed to the quality and comfort of these shoes. I could not buy anything else. There are a bit narrow though and one may want to make sure they fit well before choosing the size.
